更に、本発明の第１のヒートシンク３１後管体３１Ａは、熱伝導に優れた黄銅製の口金である電源接続手段６を介して熱を電球ソケットなどに伝達することができる。即ち、後管体３１Ａは電球ソケットに固定される取り付け機能と、熱を一時収容して熱容量を高める機能と、収容した熱を電球ソケットなどに伝達する機能とを兼ね備えている。 Furthermore, the first heat sink 31 rear tube body 31A of the present invention can transmit heat to a light bulb socket or the like via the power supply connection means 6 which is a brass cap having excellent heat conduction. That is, the rear tube body 31A has an attachment function fixed to the light bulb socket, a function of temporarily storing heat to increase the heat capacity, and a function of transmitting the stored heat to the light bulb socket.
図４〜図６では本発明の第２の実施形態の照明装置が示されており、図４はその一部構成を示す分解図であり、図５は同部分の分解断面図であり、図６は組み立てた状態の断面図である。 4 to 6 show a lighting device according to a second embodiment of the present invention, FIG. 4 is an exploded view showing a part of the configuration, and FIG. 5 is an exploded sectional view of the same part. 6 is a cross-sectional view of the assembled state.
図４〜図６に示されているように、本発明の第２の実施形態は第１の実施形態と類似する構成を有しているので、以下ではその相違点のみについて詳しく説明する。 As shown in FIGS. 4 to 6, the second embodiment of the present invention has a configuration similar to that of the first embodiment, and only the differences will be described in detail below.
第１のヒートシンク３１の前管部３１Ｂの両端に、それぞれ断熱スリーブ３０が一つずつ端部から管内に挿し込まれるように取り付けられている。 The heat insulating sleeves 30 are attached to both ends of the front pipe portion 31B of the first heat sink 31 so as to be inserted into the pipe from the end portions one by one.
断熱スリーブ３０は、断熱材料により形成されているものであって、前管部３１Ｂの管内に挿し込むことができるように構成されている円環状のスリーブ部３０１と、スリーブ部３０１の一端から第１のヒートシンク３１の前管部３１Ｂの形状に対応する六角形の周縁を有するように張り出し、且つスリーブ部３０１が他端から前管部３１Ｂの管内に挿し込まれるとその内面が第１のヒートシンク３１の前管部３１Ｂの前端面または後端面に当接してその六角形の周縁が前管部３１Ｂの六角形の周縁と一致することができるように構成されている取付板部３０２とを有する。 The heat insulating sleeve 30 is formed of a heat insulating material and is configured to be inserted into the tube of the front pipe portion 31B. When the sleeve portion 301 is inserted into the tube of the front tube portion 31B from the other end, the inner surface of the first heat sink 31 is extended to have a hexagonal periphery corresponding to the shape of the front tube portion 31B of the first heat sink 31. And a mounting plate portion 302 configured to be in contact with the front end surface or the rear end surface of the front tube portion 31B of the 31 and the hexagonal periphery thereof to coincide with the hexagonal periphery of the front tube portion 31B. .
前管部３１Ｂの前端に取り付けられている断熱スリーブ３０の前端に第２のヒートシンク３２が当接するように取り付けられており、前管部３１Ｂの後端に取り付けられている断熱スリーブ３０の後端には、複数の放熱孔３９１を有する放熱プレート３９が当接している。 The second heat sink 32 is attached so as to abut the front end of the heat insulating sleeve 30 attached to the front end of the front pipe portion 31B, and the rear end of the heat insulating sleeve 30 attached to the rear end of the front pipe portion 31B. A heat radiating plate 39 having a plurality of heat radiating holes 391 is in contact therewith.
第３のヒートシンク３３は、断熱スリーブ３０のスリーブ部３０１より小径な管状に形成され、２つの断熱スリーブ３０の間に保持されると共に、その外側から第２のヒートシンク３２と放熱プレート３９とにより挟まれている。 The third heat sink 33 is formed in a tubular shape having a smaller diameter than the sleeve portion 301 of the heat insulating sleeve 30, is held between the two heat insulating sleeves 30, and is sandwiched between the second heat sink 32 and the heat radiating plate 39 from the outside. It is.
また、第２のヒートシンク３２には、第３のヒートシンク３３の管内空間と連通できる複数の通気孔３２１が形成されており、第２のヒートシンク３２に取り付けられている第２の回路基板４２にも通気孔３２１と連通できる通気孔４２１が形成されている。 The second heat sink 32 is formed with a plurality of vent holes 321 that can communicate with the space inside the pipe of the third heat sink 33, and the second circuit board 42 attached to the second heat sink 32 is also provided. A vent hole 421 that can communicate with the vent hole 321 is formed.
この構成により、第２のヒートシンク３２と第３のヒートシンク３３は、共に第１のヒートシンク３１から断熱されるようになり、発光ユニット４３から第１のヒートシンク３１に伝わった熱は直接に第２のヒートシンク３２及び第３のヒートシンク３３に伝わらず、第１のヒートシンク３１との間に温度差を作り出すことが出来、第１のヒートシンク３１の管内の第３のヒートシンク３３との間の空間における空気の対流効果を高めることが出来る。また、第１のヒートシンク３１の管内の第３のヒートシンク３３との間の対流空間３８において加熱される空気は、第３のヒートシンク３３と断熱スリーブ３０のスリーブ部３０１との間の隙間と、第２のヒートシンク３２にある通気孔３２１と、第２の回路基板４２にある通気孔４２１とを経由して、第１のヒートシンク３１の管外へ流れることができ、更に高い放熱性を有することができる。 With this configuration, both the second heat sink 32 and the third heat sink 33 are insulated from the first heat sink 31, and the heat transmitted from the light emitting unit 43 to the first heat sink 31 directly becomes the second heat sink 31. A temperature difference can be created between the first heat sink 31 and the third heat sink 33 without being transmitted to the heat sink 32 and the third heat sink 33, and the air in the space between the first heat sink 31 and the third heat sink 33 can be created. The convection effect can be enhanced. In addition, the air heated in the convection space 38 between the first heat sink 31 and the third heat sink 33 in the pipe, the gap between the third heat sink 33 and the sleeve portion 301 of the heat insulating sleeve 30, It can flow out of the tube of the first heat sink 31 via the vent hole 321 in the second heat sink 32 and the vent hole 421 in the second circuit board 42 and has higher heat dissipation. it can.
図７では本発明の第３の実施形態の照明装置の断面図が示されており、図示されているように、この第３の実施形態は第１の実施形態とほぼ同じ構成を有しており、その相違点はバルブ２の形状が異なっていることにある。即ち、本発明の照明装置におけるバルブの形状には特に制限がなく、様々な形状に形成することができる。 FIG. 7 shows a cross-sectional view of a lighting device according to a third embodiment of the present invention. As shown, this third embodiment has substantially the same configuration as the first embodiment. The difference is that the shape of the valve 2 is different. That is, the shape of the bulb in the lighting device of the present invention is not particularly limited, and can be formed in various shapes.
上記構成による本発明の照明装置は、直管状の第１のヒートシンクの前端部の外周面に取り付けられている第１の回路基板と、第１のヒートシンクの前側にある第２のヒートシンクに取り付けられている第２の回路基板との２つの回路基板に、それぞれ第１のヒートシンクの周りへの光の放射と第２のヒートシンクの前方への投光が可能な複数の発光ユニットを配置しているので、従来より照明範囲が広く、その上第１、第２のヒートシンクの熱対策により高い放熱性を有するので従来より使用寿命が長い照明装置を提供することができる。 The illuminating device of the present invention having the above configuration is attached to the first circuit board attached to the outer peripheral surface of the front end portion of the straight tubular first heat sink and the second heat sink on the front side of the first heat sink. A plurality of light emitting units capable of emitting light around the first heat sink and projecting light in front of the second heat sink are arranged on two circuit boards, the second circuit board and the second circuit board, respectively. Therefore, since the illumination range is wider than the conventional one, and the first and second heat sinks have a higher heat dissipation property, it is possible to provide an illuminating device having a longer service life than the conventional one.
